Commercial Aircraft Programs

At December 31, 2025 and 2024, commercial aircraft programs inventory included the following amounts related to the 737 program: deferred production costs of $11,777 and $9,679 and unamortized tooling and other non-recurring costs of $750 and $909. At December 31, 2025, $12,490 of 737 deferred production costs, unamortized tooling and other non-recurring costs is expected to be recovered from units included in the program accounting quantity that have firm orders, and $37 are expected to be recovered from units included in the program accounting quantity that represent expected future orders.

At December 31, 2025 and 2024, commercial aircraft programs inventory included the following amounts related to the 777X program: $4,313 and $3,476 of work in process (including deferred production costs of $651 and $0) and $1,816 and $4,122 of unamortized tooling and other non-recurring costs. In April 2022, we decided to pause production of the 777X-9 during 2022 and 2023, which resulted in abnormal production costs of $513 during the year ended December 31, 2023. In the fourth quarter of 2023, the 777X program resumed production and, as a result, there were no abnormal production costs during the years ended December 31, 2025 and 2024. During the years ended December 31, 2025 and 2024, we determined that estimated costs to complete the 777X program plus the costs already included in 777X inventory exceed estimated revenues from the program. The resulting reach-forward loss of $4,899 in 2025 was recorded as a reduction of deferred production costs, unamortized tooling and other non-recurring costs. The reach-forward loss of $3,499 in 2024 was recorded as a reduction of deferred production costs and other non-recurring costs. The level of profitability on the 777X program will be subject to several factors. These factors include aircraft certification requirements and timing, flight test discoveries, design changes, change incorporation on completed aircraft, production disruption due to labor instability and supply chain disruption, customer considerations, delivery timing and negotiations, further production rate adjustments for the 777X or other commercial aircraft programs, and any change in the accounting quantity. One or more of these factors could result in additional reach-forward losses in future periods.

At December 31, 2025 and 2024, commercial aircraft programs inventory included the following amounts related to the 787 program: deferred production costs of $13,859 and $13,178, supplier advances of $932 and $1,379, and unamortized tooling and other non-recurring costs of $1,366 and $1,370. At December 31, 2025, $13,027 of 787 deferred production costs, unamortized tooling and other non-recurring costs are expected to be recovered from units included in the program accounting quantity that have firm orders, and $2,198 are expected to be recovered from units included in the program accounting quantity that represent expected future orders. We expensed abnormal production costs of $30, $256, and $1,014 during the years ended December 31, 2025, 2024 and 2023.

Commercial aircraft programs inventory included amounts credited in cash or other consideration (early issue sales consideration) to airline customers totaling $6,412 and $5,837 at December 31, 2025 and 2024.
